Norio Taniguchi

Norio Taniguchi is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Norio Taniguchi rather than just read about it. In short: Norio Taniguchi (谷口紀男, Taniguchi Norio; May 27, 1912 – November 15, 1999) was a professor of Tokyo University of Science. He coined the term nano-technology in 1974 to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer: nano-technology "mainly consists of the processing of separation, consolidation, and deformation of mate…

Key takeaways

Norio Taniguchi belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Norio Taniguchi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Norio Taniguchi from memory before moving on to harder problems.

Reference excerpt

Norio Taniguchi (谷口紀男, Taniguchi Norio; May 27, 1912 – November 15, 1999) was a professor of Tokyo University of Science. He coined the term nano-technology in 1974 to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer: nano-technology "mainly consists of the processing of separation, consolidation, and deformation of materials by one atom or one molecule." Taniguchi started his research on abrasive mechanisms of high precision machining of hard and brittle materials. At Tokyo University of Science, he went on to pioneer the application of energy beam techniques to ultra precision materials processing; these included electro discharge, microwave, electron beam, photon (laser) and ion beams. He studied the developments in machining techniques from 1940 until the early 1970s and predicted correctly that by the late 1980s, techniques would have evolved to a degree that dimensional accuracies of better than 100 nm would be achievable.

Recognition The European Society for Precision Engineering and Nanotechnology presented Professor Taniguchi with its 1st Lifetime Achievement Award in Bremen, May 1999.

The citation on Professor Taniguchi's award read: In recognition of his unique and outstanding contributions to research and development in the ultra precision materials processing technologies and in 1974, being the first to formulate and use the term Nanotechnology. Through his vision, writings and example of total dedication to his field of endeavour he has stimulated the development of what will be one of the dominant technologies of the 21st Century.

Worked examples

Example 1 — a first encounter with Norio Taniguchi

Start with the simplest possible case. Write down what Norio Taniguchi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Norio Taniguchi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Norio Taniguchi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Norio Taniguchi

In research: Norio Taniguchi appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Norio Taniguchi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Norio Taniguchi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1912 births, 1999 deaths, Japanese scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Norio Taniguchi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
